For the past few months, there's been a cool Twitter hashtag circulating among the Japanese language Twitterverse.

The tag is #なぜ描いたかわからないイラスト晒せ (Naze Kaita ka Wakaranai Irasuto Sarase), which translates to "Exposé of Illustrations I Don't Know Why I Drew".

The hashtag is rather interesting because people continue to add to it, keeping things fresh and fun. Also, professional illustrators, such as Lollipop Chainsaw character designer NekoshowguN, toss up doodles that they have no clue why they created.

Below, you can see some of the creations that appeared under the hashtag.
